Azure AD Conditional Access policies for Office 365 (Exchange and SharePoint Online) is now available in preview; additional services may be supported (see at the end of this post).

This will make it easier to request multi-factor authentication when accessing Office 365 services. Until then, either you had to manage it at the ADFS level if you were using federated authentication or you were not able to define such conditional access if you were using Office 365 authentication.

Requirements

Before setting up Azure AD Conditional Access policies you need to ensure that your devices will be supported:

Setup Conditional Access Policies (Cloud Authentication)

Logon to your Azure administration portal (“old” version) using your Office 365 admin account (or Azure AD admin account) – https://manage.windowsazure.com
